As further shown in FIG. 1B, the vapor generator assembly 110 mayinclude an inlet port 152, extending through the outer housing 111 ofthe vapor generator assembly 110, and a conduit 158, coupling inletports 152, 132, that are configured to direct air from an exterior ofthe vapor generator assembly 110 (e.g., an ambient environment) to flowinto the vaporizer assembly 130, via at least inlet port 132 in theouter housing 131 of the vaporizer assembly 130, to flow in fluidcommunication with the heater 136. In some example embodiments, whereinthe outer housing 111 of the vapor generator assembly 110 includes theouter housing 131 of the vaporizer assembly 130, the inlet port 152 andconduit 158 may be omitted from the vapor generator assembly 110 and theinlet port 132 may be directly exposed to the exterior of the vaporgenerator assembly 110 (e.g., an ambient environment).

Thus, the reservoir assembly 102 may beconfigured to enable refilling of the reservoir 112 via introduction ofpre-vapor formulation into the reservoir 112 through at least the fluidport 114, thereby enabling pre-vapor formulation to be introduced intothe reservoir 112 independently of the vaporizer assembly 130 and/orconduit 140.

Additionally, as noted above, the reservoir assembly 102 may beconfigured to enable supplying of pre-vapor formulation from reservoir112 to the vaporizer assembly 130 via fluid port 134, to enable thevaporizer assembly 130 to generate a vapor based on the heater 136heating at least a portion of pre-vapor formulation supplied to thevaporizer assembly 130 from the reservoir 112.

Still referring to FIGS. 1A-1B, the isolation structure 116 isconfigured to move (e.g., is configured to be movable) in relation toboth the reservoir 112 and the vaporizer assembly 130 to expose fluidport 114 while covering fluid port 134, to cover fluid port 114 whileexposing fluid port 134, and/or to cover both the fluid port 114 and thefluid port 134 at the same time. In some example embodiments, isolationstructure 116 cannot cover both the fluid port 114 and the fluid port134 at the same time. In some example embodiments, the isolationstructure 116 may be movable to expose either the fluid port 114 or thefluid port 134, but not both at a given time. In some exampleembodiments, the isolation structure 116 is configured to precludesimultaneous exposure of fluid port 114 and fluid port 134. In someexample embodiments, the isolation structure 116 is configured to moveto cover both the fluid port 114 and the fluid port 134 at the sametime. In some example embodiments, fluid port 114 may include more thanone port (e.g., there may be multiple fluid ports 114), and/or fluidport 134 may include more than one port (e.g., there may be multiplefluid ports 134), and the functionality described above can similarlyapply. For example, the isolation structure 116 may be configured tomove to expose the one or more fluid ports 114 while covering the one ormore fluid ports 134, to cover the one or more fluid ports 114 whileexposing the one or more fluid ports 134, and/or to cover the one ormore fluid ports 114 and the one or more fluid ports 134 at the sametime.

In some example embodiments, the isolation structure 116 is configuredto move to expose the reservoir 112 to either an exterior of thereservoir 112 via fluid port 114, or to the vaporizer assembly 130 viafluid port 134, both not both at a given time, for example, to isolatethe reservoir 112 from the vaporizer assembly 130 based on coveringfluid port 134 while exposing fluid port 114, and thereby enablingrefilling of the reservoir 112 through fluid port 114 while precludingtransfer of pre-vapor formulation from the reservoir 112 to thevaporizer assembly 130, or for example, to expose the reservoir 112 tothe vaporizer assembly 130 by exposing fluid port 134 while coveringfluid port 114, thereby isolating the reservoir 112 from an exterior ofthe reservoir 112 via fluid port 114 while enabling pre-vaporformulation to be drawn from the reservoir 112 to the vaporizer assembly130 to enable generation of a vapor at the vaporizer assembly 130 basedon heating the drawn pre-vapor formulation while precluding transfer ofpre-vapor formulation between the reservoir 112 and an exterior of thereservoir 112 via fluid port 114. In some example embodiments, theisolation structure 116 may be configured to cover both fluid port 114and fluid port 134 simultaneously. In some example embodiments, fluidport 114 may include more than one port (e.g., there may be multiplefluid ports 114), and/or fluid port 134 may include more than one port(e.g., there may be multiple fluid ports 134), and the functionalitydescribed above can similarly apply. For example, the isolationstructure 116 may be configured to move to expose the reservoir 112 toeither an exterior of the reservoir 112 via one or more fluid ports 114while covering the one or more fluid ports 134, to expose the reservoir112 to the vaporizer assembly 130 via the one or more fluid ports 134while covering the one or more fluid ports 114, and/or to isolate thereservoir 112 from both the exterior of the reservoir 112 and thevaporizer assembly 130 by covering both the one or more fluid ports 114and the one or more fluid ports 134 at the same time.

Still referring to FIGS. 1A-1B, an example power supply assembly 120 mayinclude a power supply 122. The power supply 122 may be a rechargeablebattery, and the power supply assembly 120 may be configured to supplyelectrical power from the power supply 122 to the vapor generatorassembly 110 (e.g., to the heater 136 via one or more electrical leads)to support vapor generation at the vaporizer assembly 130.

As shown in FIG. 1B, an example e-vaping device 100 may include aninstance of control circuitry 124 that may be configured to control thesupply of electrical power from the power supply 122 to the vaporgenerator assembly 110 (e.g., to the vaporizer assembly 130). In theexample embodiments shown in FIG. 1B, the control circuitry 124 isincluded in the power supply assembly 120, but it will be understoodthat, in some example embodiments, the control circuitry 124 may beincluded in the vapor generator assembly 110 instead of the power supplyassembly 120.

FIG. 3A is a perspective of a reservoir assembly102 according to some example embodiments. FIG. 3B is a cross-sectionalview along line IIIB-IIIB′ of the reservoir assembly 102 of FIG. 3Aaccording to some example embodiments. FIG. 4A is a perspective view ofa reservoir assembly 102 according to some example embodiments.

In some example embodiments, an isolation structure 116 of a reservoirassembly 102 includes multiple structures that are coupled together toform the isolation structure 116, or one structure with different parts(e.g., while reference is made to one or more structures, one or more ofthese could form part of the same structure). The isolation structure116 may include a first structure 210 and a second structure 220. Thefirst structure 210 may be configured to move to either expose or coverthe fluid port 114. The second structure 220 may be configured to moveto either expose or cover the fluid port 134. The isolation structure116 may further include a coupling structure 230 that couples the firststructure 210 and the second structure 220 together, such that movementof the isolation structure 116 includes movement of the first structure210 together with the second structure 220 in unison via the couplingstructure 230. As shown in FIGS. 2A-3B, the coupling structure 230 maybe a hollow structure that encloses at least a portion of conduit 140within an interior thereof, but it will be understood that exampleembodiments are not limited thereto.

In some example embodiments, the isolation structure 116 may omit thefirst or second structures 210, 220. In some example embodiments, forexample where the isolation structure 116 includes the second structure220 but omits the first structure 210, the second structure 220 may bereferred to as a “first structure” of the isolation structure 116. Evenwhen both structures 210, 220 are included, the structures should not belimited by the terms “first,” “second,” etc. As noted already, the terms“first,” “second,” etc. are only used to distinguish one element orstructure from another, and thus, a first structure could be termed asecond structure, and vice-versa.

In FIGS. 2A-2B and FIGS. 3A-3B, the isolation structure 116 isillustrated such that example embodiments of the first structure 210 areshown in detail and the second structure 220 is shown in the abstractthrough a dashed-line representation, while FIGS. 4A-4B and FIGS. 5A-5Billustrate the isolation structure such that example embodiments of thesecond structure 220 are shown in detail and the first structure 210 isshown in the abstract through a dashed-line representation, to show thatan isolation structure 116 of FIGS. 2A-3B may include any exampleembodiment of a second structure 220 (e.g., including any of the exampleembodiments of a second structure 220 shown in FIGS. 4A-5B), includingan omission of a second structure 220 from the isolation structure 116,and an isolation structure 116 of FIGS. 4A-5B may include any exampleembodiment of a first structure 210 (e.g., including any of the exampleembodiments of a first structure 210 shown in FIGS. 2A-3B), including anomission of a first structure 210 from the isolation structure 116.

Referring first to some example embodiments, including the exampleembodiments shown in FIGS. 2A-2B, an isolation structure 116 may includea first structure 210 and a second structure 220 coupled via a couplingstructure 230, where the first structure 210 is a disc structure thatincludes a fluid port 214 extending through the disc structure of thefirst structure 210. The isolation structure 116 may be configured tomove (e.g., based on rotating 240 the isolation structure 116 around alongitudinal axis 250 of the isolation structure 116) to move firststructure 210 to adjustably align or at least partially align fluid port214 with fluid port 114 or to cover fluid port 114 with the discstructure of first structure 210, such that the first structure 210either exposes fluid port 114 based on fluid port 214 at least partiallyaligning with fluid port 114 or isolates fluid port 114 through the discstructure of the first structure 210. Thus, the isolation structure 116may expose the reservoir 112 to, or isolate the reservoir 112 from, anexterior of at least the reservoir 112 through fluid port 114 based onisolation structure 116 moving to adjustably align or mis-align fluidport 214 of the first structure 210 with fluid port 114.

The isolation structure 116 maybe configured to move (e.g., based on rotating 240 the isolationstructure 116 around a longitudinal axis 250 of the isolation structure116) to move the protrusion structure 210 to adjustably cover fluid port114 or to at least partially expose fluid port 114, such that the firststructure 210 either isolates fluid port 114, or exposes fluid port 114.Thus, the isolation structure 116 may expose the reservoir 112 to, orisolate the reservoir 112 from, an exterior of at least the reservoir112 through fluid port 114 based on isolation structure 116 moving toadjustably mis-align or align first structure 210 with fluid port 114.

It will be understood that the first structure 210, the second structure220, and the coupling structure 230 may be included in a commonstructure to form the isolation structure 116. The common structure maybe a unitary piece of material.

Referring now to some example embodiments, including the exampleembodiments shown in FIGS. 4A-4B, an isolation structure 116 may includea first structure 210 and a second structure 220 coupled via a couplingstructure 230, where the second structure 220 is a disc structure thatincludes a fluid port 224 extending through the disc structure of thesecond structure 220.

The isolation structure 116 may be configured to move (e.g., based onrotating 240 the isolation structure 116 around a longitudinal axis 250of the isolation structure 116) to move second structure 220 toadjustably align or at least partially align fluid port 224 with fluidport 134 or to cover fluid port 134 with the disc structure of secondstructure 220, such that the second structure 220 either exposes fluidport 134 based on fluid port 224 at least partially aligning with fluidport 134 or isolates fluid port 134 through the disc structure of thesecond structure 220. Thus, the isolation structure 116 may expose thereservoir 112 to, or isolate the reservoir 112 from, an exterior of atleast the reservoir 112 through fluid port 134 based on isolationstructure 116 moving to adjustably align or mis-align fluid port 224 ofthe second structure 220 with fluid port 134.

The isolation structure 116 maybe configured to move (e.g., based on rotating 240 the isolationstructure 116 around a longitudinal axis 250 of the isolation structure116) to move the protrusion structure 220 to adjustably cover fluid port134 or to at least partially expose fluid port 134, such that the secondstructure 220 either isolates fluid port 134, or exposes fluid port 134.Thus, the isolation structure 116 may expose the reservoir 112 to, orisolate the reservoir 112 from, an exterior of at least the reservoir112 through fluid port 134 based on isolation structure 116 moving toadjustably mis-align or align second structure 220 with fluid port 134.

As shownin FIGS. 6A-6B, the second structure 220 may also include a discstructure 615, and the cylindrical structure 620 may extend coaxiallyfrom the disc structure 615, but example embodiments are not limitedthereto. As shown in FIGS. 6A-6B, second structure 220 may include afluid port 634 that extends through the cylindrical structure 620. Thecylindrical structure 620 may be configured to align fluid port 634 withfluid port 134 based on the cylindrical structure 620 being rotated 240around the longitudinal axis 250. Accordingly, the isolation structure116 may be configured to be moved (e.g., based on rotating 240 theisolation structure 116 around the longitudinal axis 250, which may be alongitudinal axis of the isolation structure 116) to rotate thecylindrical structure 620 around the longitudinal axis 250 to thusrotate the cylindrical structure 620 around the side surface 130 s ofthe vaporizer assembly 130 to adjustably align or at least partiallyalign fluid port 634 with fluid port 134 or to mis-align fluid port 634with fluid port 134 such that the cylindrical structure 620 covers thefluid port 134, such that the second structure 220 either exposes fluidport 134 through at least partially-aligned fluid port 634 or isolatesfluid port 134 through the cylindrical structure 620 of the secondstructure 220. Thus, the isolation structure 116 may expose thereservoir 112 to, or isolate the reservoir 112 from, the vaporizerassembly 130 through fluid port 134 based on the isolation structure 116moving to adjustably align or mis-align fluid port 634 with fluid port134. In some example embodiments, structures 620 and 615 may be separatestructures joined together, and in some example embodiments structures620 and 615 may form part of the same structure, which may be a unitarypiece of material.

As shown in FIGS. 7A-7B, the cylindrical protrusionstructure 640 may be configured to be adjustably aligned or mis-alignedwith fluid port 134 based on the isolation structure 116 being rotated240 around the longitudinal axis 250. Accordingly, the isolationstructure 116 may be configured to be moved (e.g., based on rotating 240the isolation structure 116 around the longitudinal axis 250) to rotatethe cylindrical protrusion structure 640 around the longitudinal axis250 to be adjustably aligned or mis-aligned with fluid port 134, suchthat the second structure 220 either covers fluid port 134 or exposesfluid port 134. Thus, the isolation structure 116 may expose thereservoir 112 to, or isolate the reservoir 112 from, the vaporizerassembly 130 through fluid port 134 based on the isolation structure 116moving to adjustably mis-align or align cylindrical protrusion structure640 with fluid port 134.
